Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
As boaters, what a remarkable opportunity we have to experience whales swimming free in the ocean. Winter is the peak period for whale watching along the Pacific Coast. California gray whales (eschrichtius robustus) in the Eastern Pacific number about 18,000, with another 6,000 located off Japan. Grays are by far the most frequently spotted whales off the U.S. West Coast, by a factor of 10.
